On functions starlike with respect to $n$ -ply symmetric, conjugate and symmetric conjugate points

Somya Malik, Vaithiyanathan Ravichandran

For given non-negative real numbers $α_{k}$ with $\sum_{k = 1}^{m} α_{k} = 1$ and normalized analytic functions $f_{k}$ , $k = 1, \dots, m$ , defined on the open unit disc, let the functions $F$ …

Starlikeness of a product of starlike functions with non-vanishing polynomials

Somya Malik, V. Ravichandran

For a function $f$ starlike of order $α$ , $0 ⩽ α < 1$ , a non-constant polynomial $Q$ of degree $n$ which is non-vanishing in the unit disc $D$ and $β > 0$ , we consider…

The Booth Lemniscate Starlikeness Radius for Janowski Starlike Functions

Somya Malik, Rosihan M Ali, V. Ravichandran

The function $G_{α} (z) = 1 + z / (1 - α z^{2})$ , \, $0 \leq α < 1$ , maps the open unit disc $D$ onto the interior of a domain known as the Booth lemniscate. Associated with this function…

Criteria for Starlikeness Using Schwarzian Derivatives

Asha Sebastian, V. Ravichandran

For a normalised analytic function f defined on the open unit disk in the complex plane, we determine several sufficient conditions for starlikeness in terms of the quotients Q_{ST…
